有很多人有类似的问题,我过去曾经在其他机器上遇到其中一个并且没有一个解决方案似乎有效 – 我似乎也有比其他有类似问题的人有不同的错误：

Gem files will remain installed in /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/gems/therubyracer-0.12.2 for inspection.
Results logged to /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/extensions/x86_64-darwin-14/2.0.0/therubyracer-0.12.2/gem_make.out
运行时：
gem install therubyracer -v '0.12.2'
或者干脆
bundle install
我的宝石文件中包含了therubyracer.
我正在运行Yosemite 10.10.3,Ruby 2.0.0-p353,我已经卸载了所有内容并尝试了gem install libv8 – –with-system-v8解决方案经常遇到这类问题但是没有找到解析度.
